This invention relates to card perforating machines in which a punch set-up is made for all the information to be punched before t-he punching operation takes place and in which provision is made for automatically erasing the set-up later in the cycle of operation of the machine.

The principal object of this invention is the provision of improved means for perforating twocards with the same information and for discharging the cards into separate card receptacles.

Another object of this invention is. to employ electrical connections to control the machine to punch two cards according to one set-up and to discharge these cards into separate receptacles.

Still another object of this inventionis the application of such mechanism to a machine of the type shown in lLetters Patent of the United States #1,684,546 granted lto me Sept. 18, 1928.

To the above and other ends which will hereinafter appear my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and particularlypointed out in the appended claims.

Other objects will appear from the following description taken in connection with the accompanying drawings in which,

Fig. 1 is a front view of the machine showing a portion of the mechanism of the present invention applied thereto,

Fig. 2 is an end view of the same as seen from the right-hand in Fig. 1 and with parts broken away and in section, f i

` Fig. G is a detail, fragmentary, perspective view which shows portions of the card de- 5 flector and operating means therefor, and

Fig. 7 shows a diagram of the circuits controlling the one and two card operations.

The drawings disclose only so much of the old mechanism asis necessary for a clear understanding of the invention.

The keyboard 10 is Generally the same as that shown in Letters latcnt of the United States #1,684,001 granted to Weiland et al. Sept. .11, 1928, and comprises numeral ,and alphabet keys, and a one ,trip key 11 and a w two trip key'12 which will be described` hereinafter.

The numeral and alphabet keys when depressed make circu'its as shown in the patent to Veiland et al. through solenoids in a .5

housing 13 which operate the usual Bowden wires Lito actuate levers 15 to set up set-bars for controlling perforating as is well understood. The levers 153.` actuate a common bail or universal bar 16 to2 operate an escapement 70 lever 17 to control Athe lusual escapement pawls or dogs and permit the carriage 18 to be drawn one punch-hole column to the right by the usual spring drum 19 (Fig. 2) ywhen.- ever any set-bar is depressed.

In earlier types of machines the carriage 18 was returned to the left to erase the set-up by a lever 20 (Fig. l) which through a link 21 rocked the erasing lever 22 to bring the wiping roller 23 successively into contacten with inclined faces of pawlsv 24 to swing said pawls and operate holding detents (not shown) to release the set-up set-bars.

In the machine shown in the Lasker patent this is accomplished automatically upon '85 depression of a carriage return key or in an operating cycle initiated by a trip jkey and which includes a regular punching oper-v ation. As shown in this patent, this mechanism comprises a carriage return block 25 90 `(Fig. 1) carrying a cam lug 26 for enga ement with a roller -27 on the leverl20 or swinging the wi'pino' Vroller into position to era-se the set-up. Snaid mechanism also includes a carriage return lug28 for engaging 95 a projection 29 that is fixed to the carriage and extends forward of the lever 20 at the pivotal center thereof, such engagement of the projection 29 taking .place after the lever 20 has been rocked by the cam 26 and ref l sulting in returning the carriage 18 tothe left. The carriage return block is moved to the right by the usual tape ,85' and spring drum 86. The carriage is returned to the left by a ring magnet connected to the other end of the tape 85, and adapted to be energized to travel with a sleeve 31 on a main shaft 32. The Asleeve 31 is driven from a motor which also drives a generator to supply current of the proper voltage to ythe electrical circuits of the machine.

The circuit through the ring magnet 30 (Fig. 3) is controlled by a maonet 35, energized as later' described, whic operates a retaining lever 36 for a double knife switch carrying lever 37 connected to a spring ldrawn slide 38 which is normally urged to the vright by a spring 39 and is returned to the left as the carriage is returned home as shown in the patent to Lasker. vWhen the lever 36 is released it makes-a circuit through the magnet '30 to causethe same to be ro.-

tated by the sleeve 31 to return the carriage tothe left.

. The main shaft 32 is driven from the sleeve i 31 by a clutch mechanism 40 (Fig. 1) one member 41 of which is spring urged to press its clutchv facing into engagement with a flange 42 on the sleeve 31, and is released for such movementby a stopping pawl 43 moved into released position by a magnet 44 (Fig.

7) .in circuit withparts later referred to.

The clutch mechanism is not claimed herein and may for the pur oses 'of this invention be of any approved orm las long as it may be controlled from the magnet 44.

The,l machine may be released for a single operation by depressing the one trip key 11 (Figs. 1, 4 and 7). When this key is de .pressed with the double knife switch 46 (Figs. 1 and 7) .in the position a of Fig. 7, a circuitwill be closed through the tri magnet 44 and the double `knife switch 3 which is normally in the position shown in these figures. The energization of the trip magnet 44 releases the clutch member 4l to frictionally engage the flange 42 on the sleeve 31. This causes the machine to make lone cycle of operation. During this operation a conducting bar48 (Fig. 5) on yan insulator'cylinder 49 on the main` shaft 32 will bridge spaced spring contacts 50 and 51 closing the circuit through the carria e return magnet ,35 which ermits the ouble knife carriage return switch on the lever 37 to close th'e'circuitl through the ringv magnet `30 and cause the return of the carriage.

The two trip key 12 (Figs. 1, 4 and 7) closes the circuit through a special trip mag- .net 52 (Figs. l, 2, 5 and 7 which raises a slide 53 mounted on a brac et late 54 suitably secured to the machine. his slide 'is raised against a spring 55 stretched between a pin 56 on the slide and a pin 57 on an arm 58 formed ,witha yoke hub 59 pivoted on a stud 60 projecting from the bracket plate 54. As the slide is lifted it raisesl a link` 61 mounted at one end on the pin 56 and pivoted at its other end to an ear 62 on the plate 54, to disengage its notch 63 from the pin 57 (Fig. 5) on the .arm 58 thus `permitting this arm and the yoke hub connected therewith to be rocked counter-clockwise by the spring '55. The yoke hub 59 of the arm 58 carries the carriage return spring switch arms 50 and 51 and a trip spring switch arm 64 and when rocked counter-clockwise as indicated above moves the arms 50 and 51 away from the cyl.- inder 49 and prevents the bar 48 thereon from completing the circuit through the return. magnet as the main shaft is rotated. The switch' arms 50 and 64 in their moved position close the circuit through electrically connected-spring arms 65 and 66 on a stud 67 on the bracket plate 54 (Figs. 5 and 7) which.

'maintains the trip circuit energized and the machine in operation until this condition is changed. The switch arms'50, 51 and 64 and the circuits they control are shown in Fig. 7.

The upper end of the arm 58 is connected by a lin 70 to an arm 71 secured to a rock shaft 72 (Figs. 2 and 6) carryinga def-lector 73. Normally when the machine perforates but one card for. a set-up, the dellector is in the full line position shown in Fig. 2 so that all of these cards will be deflected into the rear pocket 74. When the two trip key 12 is depressed and the arm 58 is rocked counter-clockwise, the deflector will be moved to the dotted line position directing the first card into the front pocket 75.

- The arm 58 is restored to its homeposition during. the second cycle of operation by a cam 8O (Fig. 5) rotatable o n the stud 67 and connected to a gear 81 meshing with a pinion 82 secured to a larger gear 83 in mesh with a small "gear 84 on the main shaft 32.' Thegear reduction is two to one so 4that the cam will travel one-halfv cycle while the machine the position it would occupy at the end of they first cycle if the two trip* key had been depressed with the cam Ain the home position.

On the second cycle of operation the cam will restore the arm'58 thereby breakingy the circuit through the trip magnet 44 and allowno vmakes one operation. The cam is shown in ing the machine to come t0 rest at the end -igs ' ing i by Letters Patent, is:

trip magnet and'breaks the carriage return circuit at this point.

Operation One-card operations are made by pressing the one trip key l11. in indeterminate number of operations is maderby throwing the switch 4G' from a to b, Fig. 7. Atwo card operation is effected by pressing the two trip key 12 starting of coursewith the restor- 'cam 80 in home position. Depression of the two trip key 12 energizes the special trip magnet 52 which swings the spring contact arms and 5'1 away from the cylinder 49 to prevent the bar 48 from closing the circuit through the carriage return magnet 30. The arm 50 and the trip magnet switch arm 64 arc brought into electrical connection by spi-ing contact arms 65 and 66 Which establishes a circuit through the trip magnet 44. This condition is maintained until the cam 8O lrestores thel arm 58 andthe contacts 50, 51 and 64, placing the contacts 50 and 51 in position to be bridged by bai' 48 to cause return of the carriage and an erasing of thev set-up justA before the end of the second cycle of operation. chine is controlled to punch two cards for the saine set-up, the first card being delivered into the front pocket 75 and the second card into the rear pocket 74;
